Question

Describe an experiment to determine the acceleration of free fall using a falling body

Answer 1

The experiment to determine the acceleration of free fall using a falling body in a laboratory hooked weight is 200 g mass.

The drag on the paper strip has too extreme effect on the fall of lighter weights. The weight is suspended from 3 metres of paper tape.

Reinforce the tape with stripe of masking tape on one end.

Then punch hole 1 cm from the end in the reinforcement.

This can support 1 kg of weight with careful handling.   

Any object, which is moving, and being acted upon only be the force of gravity is said to be "in a state of free fall."

According to this, free fall leads to two important characteristics about a free-falling object: First, Free-falling objects do not encounter air resistance.

In the case of absence of air resistance, all objects in free-fall near the surface of the Earth will experience the same uniform acceleration.

Answer 2

Free fall experiment:

Aim: To measure the acceleration of a falling object.

Materials required:  

• Tape
• Timer
• Object to free fall

Procedure:

The 110-v timer is set up about 2.5m above the laboratory floor for the drop.

When the suspended weight is allowed to fall, a 110-v timer will mark equal time intervals on the tape pulled down after the weight.  

After a few practice runs, this method can be made to yield a series of dots on the tape without seriously retarding its fall.

Observation:

The time taken for the weight to reach the ground

The height of object from the ground before release
